Like his later The Finishing Line (1977), John Krish's film uses a bizarre
narrative premise to convey the message of an instructional documentary (and
indeed, the film won a Grierson Award). That message, to experienced drivers,
that driving carefully is potentially a matter of life and death, is
communicated by presenting a car journey through the eyes of the driver,
intercut with scenes of actors (including Colin Baker, who later became Dr Who
(BBC, 1963-89), and John Challis, later a regular on Only Fools and Horses (BBC,
1981-96)) supposedly representing the inner workings of his brain.

Audiences seeing the film today are likely to laugh at the 1970s campness of earlier scenes, but usually get caught up in the increasingly urgent narrative, culminating in the death of the driver.
